What would you recommend stand alone or piggy back? I eventually want to run around 10psi I think that would be safe since I drive the car every day. It has mugen cat back with stock header. I want to go with a larger throttle body and header. What's the best bang for my buck brand wise for electronics throttle body and header. Thanks for your help

 

I have aem ems and like that. You lose obdII however. That and some injector dynamic 1000cc injectors with plug and play clips would be good. You will also need a 3 or 4 bar map sensor.
If getting it tuned I would just go for the 12 psi pulley and call it a day. You will also need a clutch if you haven't upgraded yours yet.

I'd worry about header and throttle body later.

 

So I was in the process of shopping around all the extras I wanted unfortunetly some family issues have arrised and that will be put on hold but I still want to install the kit as is just need a few things and wanted some imput. The kit I got is an 04-05 kit and my S is an 02 the kit has no crank pulley, which I assume is the modified one where and how much will it cost? Also kit has no intake kit my original plan was to have one custom fabricated but wanted to save money can I just attach an hks Air filter to the blower inlet? What else would I have to do and what size or exact filter will I need? and last I understand the voltage on the comptech esm needs to be changed for my ap1 what and how will this be changed to?

 

My clutch is already upgraded as well as axles how much am I looking at cost wise with the injectors and for the ems new or used does it matter and what kind of power am I gonna be looking at rwhp with the 12psi pulley

 

I would like to pose a question as well... Im currently running a comptech novi 1000 with a stock 4.4 pulley and after-cooler. what is the smallest pulley i can go with before i have to get engine management and injectors?

 

Im sure you can upgrade, but for some people... such as ME, that didn't work and I needed an ECU and a tune.

 

Don't want to run over 7 psi on the stock injectors/ecu.

 

How ddo the eBay heat exchangers compare with the SOS? Size size, effectiveness?

 

How much boost would a 4" pulley give? Considering this is on an ap1 with an aftercooler?

 

pulley size part approximate boost
4.4" Comptech supplied size for 2.0L 6 psi (2.0L)
4.2" Comptech supplied size for 2.2L 6 psi (2.2L)
3.6" ScienceofSpeed enpp-1091.360 9 psi (2.0L), 8 psi (2.2L)
3.4" ScienceofSpeed enpp-1091.340 10 psi (2.0L), 9 psi (2.2L)
3.2" ScienceofSpeed enpp-1091.320 11 psi (2.0L), 10 psi (2.2L)
3.0" ScienceofSpeed enpp-1091.300 12 psi (2.0L), 11 psi (2.2L)
